When Helium is cooled to almost absolute (-460°F or -273°C)

 When Helium is cooled to almost absolute zero (-460°F or -273°C), the lowest temperature possible, it becomes a liquid with surprising properties: it flows against gravity and will start running up and over the lip of a glass container!

superfluid helium




We as a whole know helium as a gas for exploding inflatables and influencing individuals to talk like chipmunks, yet what the vast majority don't know is that it comes in two particular fluid states, one of which is marginal unpleasant. At the point when helium is only a couple of degrees underneath its breaking point of – 452 degrees Fahrenheit (– 269 degrees Celsius) it will all of a sudden have the capacity to do things that different liquids can't, care for spill through atom thin splits, move up and over the sides of a dish, and stay still when its compartment is spun. No longer a negligible fluid, the helium has turned into a superfluid—a fluid that streams without rubbing. 

"On the off chance that you set a glass with a fluid flowing around and you return 10 minutes after the fact, obviously, it's quit moving," says John Beamish, a test physicist at the University of Alberta in Edmonton. Particles in the fluid will crash into each other and back off. "In any case, on the off chance that you did that with helium at low temperature and returned a million years after the fact," he says, "it would even now be moving.
